Add support for VirtualBox 4.2 without munging the JPI version, and using vagrant 1.0.5

Minimal changes made to add support for VB 4.2 (mainly, using vagrant 1.0.5) I tried to leave as much in tact as possible, and I think I succeed!  My apologies for switching from git:// to https://, I am unable to use git/ssh outside of my network.
